Favorite Flower: Nigella

I just discovered this delicate, early bloomer in the past few years when friends suggested Love-in-a-Mist (Nigella damascene) seeds from our local iris farm. The foliage looks much like fennel or dill as seedlings sprout, and nigella also is called fennel flower.

Nigella Is Versatile

We grew multicolored love in a mist in our rock garden. Tim threw the seeds out in fall and by mid-spring, we had fine fern-like leaves popping up from between the rocks. Although Nigella does best in damp sandy soil, ours grew out from under rocks that make up the walls of our xeric garden. The rocks likely held moisture longer than a spot in the open might have. The rocks also trapped the tiny seeds so fewer blew away. Plus, nigella can tolerate dry conditions.

Here are the same flowers from a wider angle — in the corner to the right of the potted geranium.

But then we tried another approach – we bought a packet of Bridal Veil (Heirloom White Nigella) seeds from Renee’s Garden and sowed them in early summer in a blank spot of our vegetable garden. This soil is far better in quality, and the seeds received consistent drip watering. The flowers were taller and stunningly white, with maroon to black centers. The plants reproduce from seeds, assuming some seedheads are left on plants at the end of the season.

These heirloom bridal veil flowers thrived in our vegetable garden and the contrast of colors is gorgeous and fun.

Sow in Fall or Spring

Although most instructions for growing nigella say to sow in spring, you can sow them in fall in areas with mild winters. They need full sun and grow in zones 2 through 10. That worked well for us last year, but this winter has been dry and consistently colder, so I’m anxious to see how many reseeded in our gardens. The bridal veil flowers in our vegetable garden bloomed later in the year, but were planted later. Sowing the seeds a few weeks apart in spring and fall can help ensure constant blooming of nigella in summer.

The many colors of love in a mist add interest to the garden or flower arrangements.

Use as a Cut Flower

You can cut nigella blooms for flower arrangements, and even better, cut some of the seedheads. If you cut the flowers to enjoy indoors, leave a few blossoms on the plant so they can dry and drop seeds for the next year. If you get too many, thin them out while small. Enjoy the seedheads after flowering by cutting their stems just after flowers fade, and hang them upside down away from direct sun.

Nigella is easy to grow and a great addition to any xeric garden!

A Trip to the Dark Side of Gardening

datura bloom
Datura, or Jimson weed bloom.

When we write about gardening and post on social media, garden writers usually choose bright, pretty pink flowers or robust tomatoes as our subjects. Yet, many plant lovers can enjoy flowers and also get a kick out of growing edgier plants.

I live with one such plant lover. In fact, he loves spines and poisonous seeds so much that our daughter and son-in-law gave him Amy Stewart’s book Wicked Plants, The Weed That Killed Lincoln’s Mother & Other Botanical Atrocities (Algonquin Books, 2009) for Christmas last year. He likes to read it right before nodding off at night…

jimson weed plant
Jimson weed is not a pretty plant but the flowers are gorgeous, especially for an evening garden.

I thought I’d share with you some of Stewart’s insights into wicked plants, and list several that thrive in our entryway or rock garden.

Datura and Nightshades

Several deadly plants make up the nightshade, or Solanaceae, family. The one we grow every year (it comes back with a vengeance) is Jimson weed, or Datura stramonium. The entire plant is somewhat poisonous, but the real danger lies in the seeds inside the fruit pod that remains after the flowers fade.

I admit I love the flowers and watching hummingbird moths feed off the blooms, which open at dusk. According to Stewart, Jamestown colonists found out the hard way about the toxic alkaloids in Jimson weed. In fact, the name has evolved from its original moniker of “Jamestown weed.” The Jimson weed is the dry cousin of other toxic nightshades and grows naturally in some of the worst conditions of the desert Southwest.

Castor Bean

Castor bean (Ricinus communis) is a member of the Euphorbiaceae family. It’s known for the ricin in the plant’s beans. Eating only a few of the seeds can kill a person. Like the Jimson weed, the toxic beans grow on an otherwise gorgeous plant. In full sun, we’ve had them shoot from seed to 10 feet tall in a summer growing season. The large leaves of the plants we’ve grown turn a dark bronze color. Also like the Jimson weed, the fruit can explode when dried out and scatter the toxic seeds. if you decide to plant this potentially deadly ornamental, you must remain vigilant about cutting off the fruit. I don’t have photos of our castor beans, probably because I keep a distance. But here is a link to more information and some excellent images of the plant and beans.

Spiny Euphorbias

The spinier and spikier, the better for our sunny hallway. Relatives of the castor bean in the spurge family include the lovely Crown of Thorns (Euphorbia milii). It also has a sticky, white sap called latex that can irritate the skin. I can’t imagine any animal chomping on the thorny branches, but I’ve seen deer eat rose branches, so it’s good to make sure dogs don’t eat the euphorbia. Euphorbias also include poinsettias, which are not truly poisonous, but can cause irritation if the toxins from leaves contact your eyes or stomach problems if children or pets eat the leaves.

larkspur plants in rock garden
Larkspur plants that reseeded and bloomed in early summer.


Stewart includes larkspur among her “Dreadful Bouquet” flowers. Larkspur is a member of the Delphinium family, and sometimes, the names are interchangeable. Plains larkspur plants are found throughout high plains of New Mexico, Colorado and Wyoming. The plant has dangerous levels of alkaloids in seeds, flowers, sap and leaves and can lead to death in cattle who consume the plains flowers at and after flowering. I love the early spring blooms of larkspur, which reseed between rocks in our garden and took over most of a bed last year. I’ve never seen deer damage, and as long as I wear gloves when handling the plant and avoid taking bites of it, I’m good.

pink and violet larkspurs
I wear gloves when I tend to these pretty Larkspurs.


Oleanders are popular shrubs and hedges in warmer Southwest climates (zones 8 through 10). They have long, slender leaves and colorful flowers. Because the plants grow quickly and need little care, they’re popular choices in landscapes. The plant’s sticky sap carries several toxins, including oleandrin, which can cause nausea and vomiting and affect heartbeat. People have been known to commit suicide by eating the plant, but the main concern is to keep curious children away, since it takes eating less to make them seriously ill. It’s too cold here to grow oleander, but we have a beautiful cousin of the plant that has a similar milky sap, a Desert Rose (Adenium), that we keep as a houseplant in winter.

Adenium with blooms
The desert rose, or Adenium, is a cousin of the oleander bush.


The poppy (Papaveraceae) is a favorite Southwest plant. Many species of poppies have toxins that can hurt animals. After all, Papaver Somniferum is the plant that supplies opium. The opium poppy is illegal to grow, but seldom regulated, says Stewart. That’s largely because of how many plants it would take to supply an individual with enough opium to maintain a habit. Our poppies have spiky leaves that distinguish them from the smoother foliage of an opium poppy.

Other Common but Wicked Plants

Stewart’s book breaks down dangerous plants by plant families and other categories, such as phototoxic plants. These have sap that can burn the skin when exposed to light and include the rinds of limes and other citrus fruits.

Lobelia plant in top of container
Lobelia is an annual here with small, delicate flowers like those I placed in the top of this tiny chiminea.

One of our favorite summer annuals is Lobelia, which also is called Indian tobacco because some ingredients in the plants cause effects similar to nicotine. In small amounts, lobelia can’t hurt you, but it can be toxic in large doses if used as an herbal remedy. I also love, love, the red bird of paradise, another warm climate ornamental shrub. But Even sweet peas and tulips have toxins in various parts of the plants or bulbs.

The bottom line is this: All gardeners should use caution when choosing plants for their home or garden to make sure curious pets and children are safe (this is an extensive list of both, and toxicity ratings, from California Poison Control). On the other hand, growing a spiny or dangerous plant can appeal to adults and older children, and be a great introduction into plant care and the gardening bug!


Five Low-water Plants for Winter Birds

stellar jay in garden
Stellar jay in line for raw peanuts in late fall.

As winter drags on, birds need lots of energy and shelter from the elements and predators. The best bird habitats mix shelter, water, natural seeds and nest-building material as spring approaches. Native plants offer many of these benefits, and the more varied a landscape, the more bird-friendly it is. For example, birds in our garden “stage” their visits to feeders or the ground by moving between the thorniest rose bushes and higher trees.

woodpecker and sparrow on bird feeder
Birds use low bushes as staging spots before visiting the feeder in our redbud.

Here are five plants or plant types that make birds safer and happier when temperatures drop without adding a lot to your work, or to summer watering requirements.

stellar jay on ground in rock garden
We have lots of spots in our garden where jays hide peanuts.

Native grasses

blue grama grass meadow
Blue grama and wildflower meadow. The grama seed spreads and feeds birds, who also help disperse the seed further for us.

Replacing at least some of your turf with native grasses and other native plants helps birds and uses less water. We purposefully leave our native grasses (mostly buffalo and blue grama) long as it dies back in fall to increase  shots at reseeding and filling in bare spots. The seeds also provide food for ground-hopping birds, additional food caches for jays to hide the raw peanuts we put out, and dried grass stalks for nests before the grass greens in summer.

Ornamental grasses

Karl Foerster grass

Switchgrass, big bluestem and muhly grasses all provide seeds and nesting materials for birds. Karl Foerster feather reed grass (Calamagrostis acutiflora “Karl Foerster”) attracts birds and is a beautiful winter plant, with tall seed stalks that blow in the breeze. There are hundreds of species of the grass, and it grows in zones 5 through 9. Its water requirements are a little higher than some native grasses, but if you plant Karl Foerster grass in a rain garden or low spot, it will get more water naturally and won’t be hurt by the damp soil.

barberry foliage
Deep red barberry foliage on right contrasts nicely with gazanias.

Barberry (Berberus) is a hardy shrub with small thorns along its branches. Depending on the variety you choose, you’ll enjoy deep red or pinkish foliage. The shrubs grow in zones 3 through 8 and retain their leaves in winter in most conditions. Fragrant yellow flowers emerge in spring, and the prickly branches provide good cover for small birds. You can plant several barberries a few feet closer together than recommended to create an attractive, bird-friendly hedge.

Boxwood (Buxus) normally isn’t considered a low-water plant, and I’ve seen countless examples of boxwood to form formal hedges and designs in other areas of the country. It is an easy plant to shape, and makes such a good hedge because its evergreen foliage is so dense.  That’s also why birds love boxwood. Although boxwood might look a little formal for a native rock garden, we use ours as a foundation plant near our front door, where we want a more landscaped effect. Since it’s also on the north side of the house, I’m sure birds hide under the bush for cover. The boxwood’s protected, mostly shady location and slow growth habit help the shrub stay healthy with less water than it might need in a sunny spot.


pyracantha berries
Partially eaten berries on a pyracantha bush in fall.

Pyracantha shrubs produce berries in late fall to feed birds as temperatures drop. Also a thorny bush (sometimes called Firethorn), pyracanthas provide safe shelter for birds. What I love about the shrub is the diverse ways you can use it in a Southwest landscape. Leave it to grow naturally (maybe with some shoot trimming after rainy summers) or shape it like a hedge. We had several growing along a distant fence and Tim moved one to the front of the house. The pyracantha transplanted without a blink and just a few scratches. We leave the remaining two out in the yard in their natural state and shape the one in front of the house. I get to see the berries from my kitchen window and saw a Stellar jay eating them this past fall.

Many native shrubs  attract birds in winter. Berries, seeds and bushy cover all support wildlife. Ask your local nursery or master gardeners for the best low-water plants in your Southwest zone.

Select Plants Now for Your Xeric Garden

The new year is almost upon us, but gardeners don’t have to wait until spring to dream, plan and even shop for new plants.

Combine native xeric plants and a few container flowers for long-lasting color.

You can take some time in winter to plan your garden. Doing so usually cheers my mood and makes me feel like I’m getting something done, even if I can’t do much outside. Here are a few tips for Southwest gardeners for winter planning and shopping.

Check Out New Plant Introductions

Each year, breeders offer new plants adaptable to conditions or resistant to diseases. Many independent testing organizations and growers conduct trials to see how plants fare in harsh conditions such as heat or drought. A favorite regional source is Plant Select in Colorado. The nonprofit organization tests and creates plants for the Rocky Mountains. You can search or browse their plant selections for zone, soil type, sun exposure, water needs and other characteristics. A new 2017 selection is the Sungari redbead cotoneaster (Cotoneaster racemiflorus var. soongoricus). The shrub is a hardy plant and fall stunner in a xeriscape.

All-America Selections also releases trial information on ornamental plants and vegetables each year. Although some of the plants are not suited for New Mexico gardens, AAS includes regional winners for the Mountain/Southwest region. For example, its 2018 winners include Mexican Sunrise Hungarian Pepper F1. This past summer, I sowed 2017 national winner Dianthus Interspecific Supra Pink F1 seeds in a garden bed and the plant bloomed well into fall. You can find AAS winners at retailers that carry national brands such as Bonnie and Burpee plants or seeds (Johnny’s selected Seeds or Territorial Seed Company).

Regional growers and local nurseries often carry new plant introductions. Typically, you can learn about new plants by subscribing to the company’s newsletter or by following them on social media. High Country Gardens (whose chief horticulturalist, David Salman, is from New Mexico) recently released a list of new plants the company offers in 2018.

Finally, the Sunset Western Garden Collection is designed specifically for Western gardeners. Sunset lists a collection of waterwise plants, but you might have to do some research to find out where to buy the plants you spot there.

Order and Review Seed Catalogs

Growing plants from seed takes a little more work, but can save you money. And some plants do better grown directly in the ground (cucumbers and squash come to mind). Even though you’ll have more success and save water by growing plants suited to your region, it’s fun to shop for rare or unusual annuals for containers or other special spots in your garden. It’s much less expensive to buy seeds for plants that probably won’t make it through the winter.

Cosmos in xeric garden
Cosmos are a perfect annual to grow from seed in a xeric garden. Too much water makes them leggy. And they feed bees in bloom and birds when seeding out.

Most seed companies ship catalogs for free to anyone who requests them and I’ve been receiving mine since before the holidays. In addition, you can find online versions of most seed catalogs. Flipping through catalogs can give you great ideas about new or unusual plants or even inspire where to plant them or ideas for companion plants for a particular flower or shrub.

Read and Research

Catalogs are one source of plant ideas, but local and regional gardening books and blogs should be your go-to sources. Combining information on plants featured in your favorite gardening books with catalogs and new introductions can help you begin planning and shopping.

This scrub jay uses low-growing xeric plants for stashing peanuts.

In your research, look for ideas such as drought-tolerant plants for easy care, plants for birds and pollinators, or colors and textures you long to add to your garden. Think about herbs and vegetables your family loves and see if you can grow a variety within your space or time constraints. And always read books and websites with a critical eye for credible information and plants most likely to grow in your zone, soil type, sun exposure or water availability.

If you don’t have a good gardening book specific to your state or zone, find out if your local master gardeners have published a plant or gardening guide. And check out my Resources page for books and links on gardening in New Mexico, xeric gardening and other topics.

High Country Gardens and other regional companies offer low-water and native plants that attract hummingbirds and add color to your garden.

Shop Locally and Online

Some gardeners prefer to touch and see plants in person, at least to decide on colors or shapes they like. Just beware that some chain stores offer plants each year that aren’t suited to your region or at least offer fewer plants tested for Southwest and xeric gardens. For example, no retailers in New Mexico offer Plant Select products, but High Country Gardens sells Plant Select through its catalog and online store. Shopping, or at least researching, online also can save time. Many online catalogs have search filters. You might be able to search by plant name, bloom color, bloom time or average temperatures and rainfall.

Many online nurseries let you order now and then ship your plants at the best possible time in spring for your zone. So, there’s really no reason you can’t get a head start. Happy plant shopping!


Bring Bees to Your New Mexico Garden

Help your garden grow and even help local farmers by including native plants that attract bees and other pollinators to your yard.

bee on blanket flower

Diseases such as Colony Collapse Disorder, and other factors, have led to declining domesticated bee numbers in the United States. However, there are plenty of species of wild, or native, bees still buzzing around looking for pollen.

flowers in edible garden
This year, we planted flowers in our vegetable garden, partly for cutting and partly to attract pollinators.

Wild bees typically aren’t part of hives; they fend for themselves, living in the ground or in hollow stems of plants. Pesticides, insecticides and other dangers still can harm wild bees. Recent studies have shown that newer insecticides called neonicotinoids are absorbed by plants and can show up in pollen. Farmers and home or business owners use neonicotinoids widely to stop pests. They’re toxic to domestic and wild bees. Avoiding use of insecticides that also harm bees is one way to help bees survive and thrive in your landscape.

Here are a few other easy steps to take:

This pear tree is nearly dead, but it still provides habitat for birds and insects. We’re adding birdhouses for additional color.

Create Habitats

Since wild bees nest in soil and hollow branches, homeowners can ensure a few protected sites in their lawn for bees. This article from the Great Pollinator Project goes into detail on how to help ground nesters and other wild bees.

fallen evergreen
This fallen branch is so pretty and out of the way for us but home to critters.

Basically, some protected and sunny soil and leaving some dead branches on the ground or on shrubs such as sumac can help cavity nesters. You also can install artificial sites such as nesting blocks.

Plant Low-water Flowers

Plenty of favorite New Mexico flowers attract bees and other pollinators. Here’s a list of some of the popular choices of shrubs and flowers that grow in New Mexico gardens:


Agastache (also a big draw for hummingbirds)

Blanketflower (Gaillardia)

Catmint (Nepeta)

Globemallow (Sphaeralcea)

Hollyhock (Alcea rosea)

Penstemon (with many native species for hummingbirds too)

Speedwell (Veronica)

Agastache, or hyssop, is a hummingbird and butterfly magnet.

Barberry (Berberis)

Blue Mist Spirea (Caryopteris x clandonensis)

Fairy Duster (Calliandra eriophylla)

Lavender (Lavendula)

Ornamental cherry (Prunus)

Provide Seasonal Color

The more months or seasons you have plants that attract bees in bloom, the better. We have some native, weed-like groundcovers that bloom in early spring, typically by April 1, that attract so many bees that we hear a low buzz sound all day when sunny. Leave flowers and seedheads on some annuals well into fall and frost danger to provide food for bees and birds. Even in higher mountain regions, native species of penstemon, beebalm and yarrow can bloom well into fall, as can hardy flowers such as gaillardia and cosmos.

spring flower alyssum
This allysum takes over our land and rock garden in spring, feeding hundreds of bees.

Finally, a word about fear of bees. I get it – wasps and bees can be scary if they come after your dessert on the patio or buzz you when you get too close. But I have never had a sting while working in my garden, and the only time I recall ever being stung was when I was a child and running through the lawn barefoot. Even when I trim lavender stalks, the bees might buzz me, but don’t sting. And if you want to remove spent flowers from plants, choose low-light times of day, such as dusk, when bees are less active. Most of all, please don’t avoid plants that bees love just to keep them out of your yard. You’re not just helping bees or the environment at large, you’re supporting a mini ecosystem that makes sure tomatoes and other edible plants produce food for you and your family.

5 Drought-resistant Groundcovers

Groundcovers might not be as sexy or exciting to plant as some ornamentals, but the low-growing plants are useful and can really add to a xeric garden’s look and function.

Prairie zinnia
Prairie zinnia covers ground and rocks. Anything that grows in rocks gets by with little water!

Here are a few reasons and ways to use groundcovers:

Water savings: erosion control. On garden slopes, a low-growing groundcover slows the flow of water. Use one that’s relatively drought tolerant and the plant absorbs enough water from the flow to get by. An added bonus – slopes can be difficult to mow, and a low-growing groundcover needs less maintenance.

Water savings: mulch effect. Groundcovers cool the soil below and retain some moisture, which can work as a sort of living mulch under a tree or other plant that needs cooler roots.

Turf alternative: Groundcovers typically are less invasive and easier to control than grass, especially between flagstone or other steps.

groundcover between stones
I believe this is ajuga between flagstones in a private Atlanta garden. It creates a sort of woodland look.

Weed control. Once a groundcover blankets an area, weeds have a harder time growing in the same spot. It might not entirely eliminate them, but eventually weed seeds have a harder time getting into covered soil and receive less light.

Design element. Groundcovers can add color, year-round interest and an area of low growth in the foreground of a design or near paths. Check out this gorgeous example of creeping thyme as an alternative lawn in a xeric design.

  1. Creeping thyme (Thymus ‘Pink Chintz’). This is an excellent choice for filling in around flagstone steps or any area that takes foot traffic (see link above). In fact, several thyme varieties are considered steppable. Creeping thyme does fine with low water once it’s established, but if it receives more water, it grows more rapidly, which might help to fill in an area.

  2. Ice plant (Delosperma). The flowers of ice plants are delicate and bright, coming in yellow, bright pink or salmon and rust colors. Although some varieties of ice plant need a little more water than others, most can get by in xeric rock gardens. Ice plant is a rapid spreader and easy to maintain. If it grows outside the area you intend, just clip it off. Or pull up a stalk and its roots and move it to another spot in your garden.

    purple ice plant
    Purple iceplant in a bed on the north side of our home.
  3. Perky Sue (Tetraneuris scaposa). Although Perky Sue might not technically be a groundcover, it can spread enough to add floral color and evergreen foliage. I’ve seen this or a nearly identical plant called plenty of other names, including Hymenoxys scaposa, bitterweed, and narrow four-leaf nerve daisy. It’s also similar to the Angelita daisy (T. acaulis).

    Perky Sue
    Perky sue has silver-like foliage and yellow daisy flowers.
  4. Prairie zinnia (Zinnia grandiflora). Also called desert zinnia, this is a favorite rock garden groundcover of mine. It has tiny, thread-like leaves and bright yellow flowers. Most of all, it spreads from the previous year’s plant; you simply remove the spent foliage as the weather warms and you see new green beneath the old. It can spread up to 6 or 10 feet.

    zinnia grandiflora shadow
    Delicate, spreading and xeric. The prairie or desert zinnia.
  5. Plumbago (Ceratostigma plumbaginoides). The best part of plumbago is its fall color. The purple flowers typically bloom in early fall and then the leaves redden. Plumbago also does best in shade or part (afternoon) shade in warmer areas.
groundcovers rock gardens
Veronica is another low-spreading groundcover for rock gardens. A Perky Sue bloom is peeking out on the left — in March!

All of these groundcovers are perennial and hardy to zone 6 or cooler. Groundcovers can require some patience or money. For carpet-like coverage, you either have to plant many of them fairly close together, or ideally space new plants according to planting instructions and wait for them to fill in. Some also have minds of their own. To me, the haphazard growth is more natural looking in a rock or xeric garden. But if you’re going for a formal look, choose one that’s easier to control, such as thyme.

Plant Select’s Top High Plains and Intermountain Plants

Each year various societies present plant awards, but those of us who garden in the West and Southwest await the group of Plant Select top performers. Plant Select, which is a nonprofit joint effort of Colorado State University in Ft. Collins, the Denver Botanic Gardens and professional horticulturalists, lists five top performers at various elevations.

First, a word about why the work of Plant Select and other regional groups is so important. As I said, there are plenty of awards and lots of information in the gardening world. But, for the most part, plants emphasized by magazines and bloggers are great for East Coast and Southeastern region gardeners. It’s different in the high plains and intermountain areas of the country, where altitude, wind, and heat and cold extremes (in a single day and by season) affect plant health. And let’s not forget the water issue.

Plant Select evaluates plant performance in 53 locations throughout five Western states. Here are some of the 2016 Top Performers. See the entire list at Plant Select.

Grand Winner: Blonde Ambition Grama Grass

Blonde Ambition grama (Bouteloua gracilis ‘Blonde Ambition’ PP22,048) was introduced by New Mexico’s David Salman of High Country Gardens (American Meadows). Blue grama is a perfect low-water native grass grazed on by cattle on our Southwest ranches. Salman introduced the blonde ornamental variety in 2011, and this is the second year it has been Plant Select’s grand winner. Beginning in July, chartreuse blooms (seedheads) appear on upright stems, turning to the blonde color as they age. Watching those seedheads wave in winter winds provides xeric gardeners some year-round interest in their landscapes. Although Blonde Ambition can spread by seed, the seedlings are easily pulled up. The grass is hardy in zones 4 through 9 and deer resistant.

Top Performer at 3,000 to 5,500 Feet Elevation

Blonde Ambition also tops the list of lower elevation garden performers in the region. Number 2 on the list is a tree I’ve never grown, but want to learn more about since it also topped the list for gardens at my altitude (6,300 feet). The Hot Wings Tatarian maple (Acer tataricum ‘Gar ann’PP15,023) has bright red samaras, or fruit made of paper tissue, that bloom all summer. It’s also known for its reddish-purple fall color. The Tartarian maple is a relatively small tree, maturing to nearly 18 feet high and wide, and gets by with full sun and moderate to dry water needs. The only drawback for me is that it is not deer resistant, but I could see this gorgeous tree in any suburban garden from 3,000 to 7,000 feet in elevation and in zones 4 through 10. We still might try it, but we’ll have to fence the tree until it reaches a mature height and keep lower limbs pruned.

Top Performer at 5,501 to 7,000 Feet elevation

Although the Hot Wings maple topped the list of performers at this elevation, I would like to give a nod to No. 2 on the list – Turkish veronica (Veronica liwanensis). Veronica is an excellent low-water groundcover. Veronica is evergreen, so it covers portions of our rock garden all year long. In summer, the groundcover blooms. Turkish veronica has cobalt blue flowers above waxy leaves. It only reaches about 2 inches in height, but can spread to 18 inches wide. Although veronica is a xeric plant, its leaves look better with a little extra water in the heat of summer. Turkish veronica is hardy in zones 3 through 10 and deer resistant. The top 5 Plant Select performers at this elevation also include Blonde Ambition, Apache plume and a catmint called Little Trudy (Nepeta ‘Psfike’ PP18,904).

Top Performer in Gardens Higher than 7,000 Feet

Fernbush (Chamaebatiaria millefolium) topped the list for higher elevations. The Western native shrub is xeric once established and grows more upright with less water. It can look more formal with rounded pruning in early winter. Deadheading spent flowers also makes the plant look neater, and should be pleasant considering that the foliage has a honey-like scent. The sweet scent also deters deer. Fernbush can grow to nearly 5 feet high and wide; less water keeps it more compact. The plant thrives in full or partial sun in zones 4B through 8.

These are only a few of the top performers in the Plant Select list. Check out their site for more on current and past top performers, new plant introductions for the region and where to buy plants for High Plains and Intermountain gardens.

Watering Cacti and Succulents

Succulents are low-care starter plants for anyone easing into gardening or short on space. Best of all, they’re typically the lowest water users of the plant world. It’s often said that cacti and succulents thrive on neglect. Although that might be true when it comes to maintenance such as trimming or fertilizing, cacti and succulents do need a little attention and consistent, light watering.

Water Sparingly

The common characteristic of succulents is that they have adapted to surviving with little water. Cacti are tough, and about the only thing that will kill them (other than being munched or trampled  by wildlife) is overwatering. In general, about once a week is perfect. Set a date every Saturday morning, for instance, to water and check on indoor succulents. The best way to water container succulents is by making two trips – water your succulents once with a slow, steady stream. Don’t give them so much water that it runs out the bottom of the container, but give them enough to soak in past the surface. Then come back and give them a second drink, which makes for a deeper and more even watering.

These agave survive outdoors here in zone 6B. We don’t water them, but from time to time, nature does the job.

The best watering for outdoor succulents is through a steady drip. How much depends on conditions, just like with other plants. When heat is extreme, cacti and succulents need a little more water. When it rains, you can skip watering altogether. If you bring cacti indoors for winter, they need a little more water in a hot, dry and sunny room.

Transplanting and Repotting

Have you ever seen a photo of an avocado pit in a glass with roots sprouting from the pit? Like most plants, lots of water encourages roots to grow. The same goes when placing most new plants in the ground or a new container—extra, deep watering helps roots establish. But that’s not true of succulents. They need time to heal before you water. In fact, taking a cutting from a cactus to grow a new plant (propagating) means letting the cutting rest and dry before putting in soil!

Tim propagated many of these succulents from cuttings.

If you want a mixed arrangement indoors or out, try to make sure your cactus or succulent receives only the water it needs. In the landscape, you can mound the dirt under the plant slightly so that water drains to nearby plants with higher water needs or have a dedicated drip for the succulent that emits less water. Avoid spray irrigation, especially on succulents. In container arrangements, keep your cactus in a small plastic container half-buried in the container’s soil. This helps the gardener pour more water to flowers around the cactus than directly on it, which helps keep the cactus soil from getting soggy.

Do a Little Research

All cacti are succulents, but not all succulents are in the cactus (Cactaceae) family. In general, succulents are known for their fleshy leaves that hold water. Their leaves usually are small as well – leaving less surface for transpiration, which is the plant equivalent of evaporation.

Baby toes (Fenestraria) are so-named for their swollen ends, a classic succulent survival feature. The flowers are pretty awesome too.

Just like with trees or flowers, every type of cactus and succulent is a little different. For example, Adenium, commonly called desert rose, is a gorgeous succulent member of the Apocyanaceae family, the same one that includes oleanders. Knowing that helps: First, the only true pest of adenium is an oleander caterpillar. Second, although technically a succulent, when the plant is in full leaf and flower season, it needs a lot of energy (sun and water) and can be treated more like a tropical plant. But adeniums drop their leaves in winter, even in indoor containers. When they go dormant, they need little to no water.

The Desert Rose (Adenium) drops its leaves in winter and needs little water while dormant (resting). When it starts getting flower buds, it needs a little more.

In fact, that’s true of nearly all cacti and succulents – they need more water (and some fertilizer) during their growing/flowering periods and just enough to get by when dormant. Most will flower and grow in spring, fall and cooler parts of summer. High summer heat can make them dormant as a survival tactic.

It’s easy to research cacti and succulents in regional garden books and online, using reputable and regional sources when possible.


Although most cacti and succulents grow more slowly than typical garden or house plants, they can outgrow their pots. In addition, succulents grown in pots and watered from a tap can have problems when minerals from the water build up in the soil. That’s a second reason to repot. You can avoid the mineral build-up by using rainwater for cacti and succulents instead of tap. Be sure your plant is in a container that drains well. That means drilling holes in the bottom of any containers that lack them and filling them with planting medium only (no rock or other filtering materials at the bottom).

The split rock cactus (Pleiospilos nelii) is native to South Africa and does well in a container, as long a you cut back on water in the heat of summer and cold of winter.

Of course, soil, location or zone and other factors affect the health and water needs of cacti and succulent. But most adapt to soil and environmental conditions.

Five Starter Waterwise Plants

Need to ease into saving water in the lawn? Or just ease into gardening? As you think about next spring and ideas for improving both the look and sustainability of your lawn or garden, consider adding easy-care plants that need little to no watering. Here are five ideas:

Yarrow is an easy xeric plant

Rosemary (Rosmarinus officinalis). The woody, herbal rosemary is near the top of my list of favorite xeric plants. The only problem you can have with rosemary is if it receives too much water (or snowpack in winter). Otherwise, try a creeping rosemary near a rock or low garden wall. The stems will grow over the surface and you can trim it in spring just to keep it clean and healthy. I’ve seen bushier varieties shaped into small hedges. And man, what a great-smelling hedge! Finally, be sure to plant a rosemary near your kitchen so you can head out and clip cuttings for cooking use anytime of year (at least in zones 8 through 10). We have rosemary plants that come back each year here in zone 6B. They’re near the house in a rock garden, which helps warm them up. Plant rosemary in full sun and only water occasionally after its first season in the garden. Rosemary plants also reward you with tiny lavender-colored flowers in summer. And although I love the taste of rosemary, deer leave them alone. Bonus!

Barberry (Berberis). Barberry comes in several varieties that do well in plenty of sun (or partial shade) and low water. Berberis x ‘Tara’ Emerald Carousel is a type that grows well in alkaline soils, the kind we have here in New Mexico. Depending on the variety, barberry grows a little wider than high. Some Japanese barberries can grow tall – up to 10 feet – so consider that when selecting a plant. Barberry leaves change color with the season, and I’ve seen lime, orange and deep red varieties; they’re all stunning. Several plants along a wall can form a hedge in front of a house or fence. We like the spiky red foliage for its color and texture in our garden and deer usually avoid the plants. Barberries might need a little more water in the first year or so than some plants listed here. After that, they can handle periods of near drought or drought. All you have to do is prune them once or twice a year to keep the shape or size you like. Be sure to wear gloves!

Yarrow (Achillea). Yarrow is considered an herb, but I grow it for its easy care and stunning colors, which include white, yellow and red varieties. Moonshine yarrow has bright yellow flower clusters that you can cut for arrangements. I also pressed a few this year. This truly is one of the easiest plants to grow. Each spring, you simply cut off the dead flower stalks and clean up the plant. By mid-summer, you’ll have color. I even tried trimming spent flowers off one of our yarrow plants this year to see if that would force a second bloom sooner. But the ones I didn’t trim had more blooms in the second wave of flowers than the one I trimmed. Lesson learned. After the initial spring trimming, just leave yarrow alone. The plant also spreads but not invasively, so consider that when placing it in a design. We dug up one that was too close to another plant and transplanted it near our farm to attract butterflies and bees. It needs a little more water when first planted or transplanted. After that, it can get by with no water in all but the most severe droughts and survives winters down to zone 3.

Four-wing saltbush (Atriplex canescens). Native Americans used many parts of the native four-wing saltbush, including leaves and boiled roots, for food or medicine. It’s also useful to wildlife, grazed by deer and antelope. The name for the bush comes from the four paper-like wings that surround its seeds. There’s no real care needed for saltbush, especially in a natural garden, but you can trim it as desired. When saltbush flowers, it takes on an attractive two-tone effect. The native plant is easy to grow in any soil, and can pop up around roadways in New Mexico. Ours grows far from the garden along a fence. We don’t know if the former owners planted it or if it came up from seed. If you’re worried about it spreading, just learn to recognize the plant’s needle-like leaves and pull up any small plants in your garden or yard.

Jupiter’s beard (Centrathus ruber ‘Coccineus’). At first glance, Jupiter’s beard (also called red valerian) doesn’t look like much. The flowers rise above thin, pointed, pale-green leaves. So it’s a lot of foliage mixed in with small, coral-pink flowers. But these flowers pack a punch! They’ll bring bees and hummingbirds to your garden all summer. And they grow best in dry, hot conditions. Still, red valerian can survive frost down to zone 3, or about -30 degrees F. All you have to do is give Jupiter’s beard a sunny spot and water regularly the first spring and summer. Then you can pretty much leave it alone. We water once in spring, depending on rain. You can cut back old leaves and stalks in spring to give energy to new growth. The plant reaches about 2 feet high and wide.

Six Favorite Reseeding Flowers

Wildflowers that reseed are a perfect plant for busy and cash-strapped gardeners. Once you get them going in the garden, they’re sure to come back for years. The trick is to deadhead or cut the flowers for arrangements while in peak bloom and then let some spent flowers go to seed.

Crazy cosmos! Ours have been popping up in the same area of our rock garden for four years. By leaving most of the spent flowers on the plant into fall, they easily reseed and feed finches.

With that in mind, choose a few plants or seeds for your favorite low-water annual and enjoy the colorful rewards for years. Here are six favorites of mine, most of them in the Aster (Asteraceae) family:

No. 1: Cosmos

Start with annuals or easily grow cosmos from seed. They come in a number of colors, including several versions of pinks and purples and white. The flower is a native of Mexico and can reach various heights depending on the mix and growing conditions. With too much water, they get a little tall and leggy. Sow cosmos after your last spring frost. Let several go to seed in fall to feed birds and provide next year’s color.

No. 2: Blanketflower

Gaillardia, or blanketflower, is an annual or a perennial in zones 3 through 11. It reseeds in our garden and lawn. This drought-tolerant beauty adds yellows, orange and rust tones to the garden. The blooms attract bees and butterflies. Blanketflowers bloom best if the gardener deadheads spent flowers, cutting the stem just above the next set of leaves down the stalk. You can also cut the plant by about one-third at the end of summer instead of regularly deadheading. If you want the flowers to reseed in your garden, leave some dried heads on the plant well into fall.

Oh no, another cosmos photo. But this one shows the contrast with the earthy colored blanketflower.

No. 3: Mexican hat

Called Mexican hat or prairie coneflower, the Ratibida columnifera is yet another member of the Aster family that reseeds easily. Mexican hats can bloom all summer long with little to no water, adding earthy colored blooms to xeric gardens. They attract bees and are considered an herb with touted use to ease stomach pain or headaches. When planted from seed, they might not bloom until the second year, but will reseed. Because the seeds need cold to help them germinate, those dropping from a plant in fall in zones 4 through 9 stand an excellent chance of becoming new plants in spring.

We have different colors of blooms on our Mexican hats, from mostly yellow to more of a deep rust. As you can see, they grow right out of the rocks.

No. 4: California/Mexican gold poppy

These wildflowers in the poppy family love sun and drought, but bloom best after summer rains. We call them California poppies (Eschcholzia californica). Mexican gold poppies are a subspecies of E. californica that thrive in desert settings. Both have feathery leaves and flowers about 2 inches in diameter that resemble a cross between an oriental poppy and a tubular or cupped flower. Deadheading the remaining seedhead helps them produce more flowers, but letting the seeds develop late in summer could lead to a new stunning poppy across the yard!

No. 5: Coreopsis

Yet another member of the Aster family, coreopsis is a great self-sower. It might take over a garden in the right conditions, but our Lanceleaf Coreopsis, a classic yellow bloomer, spreads nicely in our dry climate. If you want more color, coreopsis won’t disappoint. Here, Sunset Magazine lists a dozen favorites for western gardens. Some varieties such as lanceleaf are perennials, depending on zone. They’re a fun, natural looking plant with flowers suitable for cutting.

Coreopsis blooms are similar to daisies. This plant has a few drying flower heads.

No. 6: Wild daisies

Like their relative the sunflower, native daisies in the Aster family can spread easily and pop up in unexpected locations. We have several that bloom in late fall and spread mostly by seed. The trick is recognizing these gems among a stand of weeds so you can let them grow to maturity and bloom, then reseed. Some wild daisies are invasive, but they’re easy to control in our dry climates. Bidens alba, also called common beggartick or Spanish needle, has tiny white flowers on lanky stems. They’re pretty and are touted to have herbal or medicinal uses, but as friends of mine pointed out, they have needle in their name for a reason. The seedheads not only help the flower spread, but get caught in nearly anything they touch, including dogs’ coats.

Spanish needles and asters

You don’t necessarily need to gather seeds from these flowers unless you want to try the plant in a different area. We’ve had mixed success with that, maybe because a particular flower tends to reseed where conditions are best for the plant.

wild daisy New Mexico
I think this is a cowpen daisy, but am not certain. At any rate, the flower prefers our ditchbank and likely wouldn’t grow as well in a more controlled garden.

If you’d like to grow some of these reseeding flowers in your garden, check with your local master gardeners or a regional garden book or blog to see which types grow best in your region without becoming invasive. Of course, I go with the premise that I can always thin volunteer flowers if they get out of hand. That usually only means smack-dab in the middle of a walkway…
